REFRlGRATlNG-TANK FOR TRANSPORTING MILK AND OTHER DAIRY PRODUCTS.

SPECIFICATION forming part of Letters Patent No. 425,578, dated April 15, 1890. Application filed September 6, 1889. Serial No. 323,188. (No model.)

Torall whom it may concern.'

Be it known that I, HENRY PEARSON, a citizen of the United States, residing at No. 25 Madison street, Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Refrigerating-Tanks for Transporting Milk and other Dairy Products; and I do hereby declare the following to be a full, clear, and exact description of the iiven'- tion, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in refrigerating-tanks for transporting milk and `other dairy produets.4

Referring to the accompanying drawings, forming a part of this specification, Figure l is a perspective view of my iinproved'refrigerator, a portion of the foot-board of the vehiclein which it is carried being shown; Fig. 2, a vertical longitudinal section of the refrigerator and vehicle through the compartment ct'; Fig. 3, a perspective view showing the lid of the refrigerator raised; Fig. il, a vertical longitudinal sect-ion through the compartment a2; Figs. 5 and G, detail views of the faucet and its fastening; Fig. 7, a perspective view of a slightly modified form of refrigerator.

Referring to the drawings, the letter A indicates the body of myrefrigerator. This body is made nearly as large as the box of the vehicle which is designed to carry it, andA its front end is cut away, as shown at at, to form a seat for the driver. A longitudinal partition a, divides the refrigerator-body into two compartments c. a2, as seen in Fig. 3.

C indicates the milk-can, which is of a size and shape to snugly fit the compartment a', and is provided at its forward end with an extension ci: to fit under the drivers seat, a

space being left between the top of said can and the cover of the refrigerator, which is filled with ice. The neck c is raised above the top of the can to facilitate filling and to bring its mouth above the ice to guard against the accidental entrance of' ice or water into the can. Said neck is closed by means of any suitable cover, and the cover has connected thereto a small tube ci, which projects up through a suitable aperture in the cover of the refrigerator, its purpose being to supply a small quantity of air to the can, and thus act as a vent in drawing off the contents thereof. The bottom of the can is inclined from its rear to its front end, in order that .all the milk may be drawn from the can, and is supported on inclined cleats c, in order to raise its rear end. The front end of the can is provided with a tube c2, having its interior tapered for the purpose hereinafter described, and said tube, when the can is in place, pro jects through an aperture in the front of the refrigerator and through a corresponding aperture in the front end of the wagon-body.

Imm ediately over the aperture in the wagon body is secured a raised boss D, having a central opening d and provided upon its under or inner face with two inclined or wedgeshaped flanges d d. Upon opposite sides of the central opening d and communicating therewith are slots d2 d2.

E indicates a faucet having a tapered end to fit the tapered bore of the tube c2 and provided With two lugs e e.. The faucet is inserted in the tube c2, the lugs e c passing through the slots d? (Z2, and is given apartlal turn, the lugs e c riding' over the Wedgeshaped flanges d d', thus forcing the tapered end of the faucet tightly in place in c2. The valve-plug of the faucet is squared at its top, over which fits a key I?, supported upon the front of the wagon-body by means of a staple or eye f or other similar fastening.

The can may be made sufficiently large to entirely occupy the compartment c of the refrigerator, or two or more cans may be placed therein side by side. The compartment a? may be employed fcrthe storage of cream or butter-milk, and also for the storage of cans such as are ordinarily employed in transport ing milk by railway. The forward end of this compartment under the drivers seat is provided with a series of drawers, that may be employed for carrying butter or other produce or articles.

The refrigerator is closed at its top by ad cover composed of the hinged lids g g g2 g3, which afford access to the two compartments c and c? and at both ends of the compartments. The lids g, g', and g2 are hinged to a rod 7L, whose ends lie in bearings formed in blocks h 71.2. One of these blocks, as h', is

the tube IOC provided .with a two-part bearing composed of two l metallic platesv h3 h4, each; having formed therein half of the bearing, as shown, the two plates being hinged together at one end and secured together at their other ends by means of a s'et or thu-mb screw. Thecover is placed in position by inserting one end of the rod 71. in the bearing h2 and dropping the other end in the lower half of the two-part bearing h and swinging the other member of the bearing in place and fastening it by means of the thumb-screw.

To the bottom of the refrigerator are affixed rollers fi i, which run on rails or cleats secured to the bottom of the wagon, and at the ends ofthe rails the said bottom is grooved, as at 7c k, so that when the refrigerator is pushed in placel inthe Wagon the rollers t' e' willdrop -into saidgrooves, thusallowing the refrigerator to rest squarely on its bottom. Instead of the rollers running on rails, they may restdirectly on the bottom of the Wagon.

The refrigerator is designed to entirely fill the-body of the Wagon, and can bereadily removed for cleaning and easily replaced, and While-being cleaned-or removedfor any other purpose the-Wagon may be employed for carryinga similar refrigerator to that removed or for other purposes.

In Fig. 7 I have illustrated a slightly-m odified form of refrigerator. As shown in said figure, the refrigerator is designed to be mounted directly on running-gear, instead of being placed in a Wagon, and is provided.

with a covered compartment L in front of the drivers seat for the storage'of cans or other articles. l

The refrigerator should belined with galvanized sheet-iron or with any non-conduct ingmaterial, and the bottom of the cover should have a rubber orother suitable packing to prevent the entrance of air.

What I claim isc 1. The combination, with the refrigeratorbody` A, provided at itsfrontwith the seat a and divided longitudinally into tWo compartments a a2, of the removable can C, tting Within the compartment a and provided at its forward end With an extension 0X, fitting under the seat a, and upon top at its rear end with an elevated neck c, closedby a cover provided with a vent-tube c3, and a faucet E, communicating with said can and removably connected with said can and refrigeratorbody, all constructed and. arranged substantially as shown and-described.

2. The co1nbination,-With the refrigerator A, having bearings h h2.. lupon each. side. thereof, of the .rod 7i, removably secured. inly said bearings,and the sectionalcoverhaving, 'twoor more of its hinged sections hingedto said rod, substantiallyv asshown andfdescribed.

3. The combination, in a milk-wagon.provided upon its bottom-with groovesla, of the removable refrigerator-body A, havingyse-- fcured to its undery side rollers e', adaptedfto rest in said grooves and provided with a re= movable can C, and a faucet E; communicate` ing` with said can and.. detachably connected. to the Wagon-body, substantially as shown. and described, and for the purpose specified.`
